Original application led May 20, 1916, Seriall No. 98,853. Divided and this application filed March 27,

To all whom t may concern: l

Be it known that I, OTTO THIEME, a citizen of the United States. residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Tabulating Mechanism7 of which the following is a full,

clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use thelsame, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a rear elevational view of a part of a calculating machine equipped with my improved tabulating mechanism.

Fig. 2 is a' horizontal sectional view through the same.

Fig. 3 is a rear elevational view of part of the tabulating mechanism.

Fig. 4 is a detail view of the automatic means for operating the calculating mechanism from the bar carried by the typewriter carriage.

Fig. 5 is a Side elevational view showing one of the typewriter carriage stops in section.

Fig. 6 is a side elevational view of the rear portion of the tabulating mechanism.

Fig. 7 is a side elevational view of an entire combined adding'and typewriting machine with the rear frame walls broken away to illustrate certain of the parts identified with my present invention.

This invention relatos to a new and useful improvement in tabulating mechanism for combined adding and typewriting machines of the Moon-Hopkins billing machine type, and is a division of an application filed by me May 20, 1916, Serial Number 98,853.

The parent case vdiscloses a tally roll attachment for the Moon-Hopkins billing'machine and as is well known, the Moon-Hopkins machine is a combined adding andtypewriting machine in which there is ordinarily a paper carriage 1 for supporting a sheet of paper on which the words-printing mechanism of the typewriter may make printing impressions by the Operation of the keys 2, in addition to the printing type 3 controlled by the adding mechanism to record items set up by the keys 4 and totals thereof. These items and totals are indicated by the registers wheels 119 and 268 which are operated Serial No. 224,960.

means of a spring 526 (or rightwardly as seen from the rear in Fig. 3), and said frame carries at its lower end a notched plate or escapement bar 521.

The escapement bar 521, carried by the frame 503, is provided with a series of recesses 521a and projections 521b located according to the desired stepping movement of the frame with which-recesses and projections coperates an escapement pawl 527 (see Fig. 3) in the form of a bell crank lever, said escapement `pawl being pivofted to a bracket 530 extending inwardly from the track rail 520. This track rail is cut away or recessed to permit the operation of the escapement pawl. The escapement pawl has a leaf spring member 527a secured thereto and whose Jfree rear end coperates with the projections 521b on the escapement rail., the purpose olf this spring 527a being to absorb the shock of the tally-roll carriage.

531 represents a bar slotted at each end to engage screws which find a bearing in some suitable frame members of the machine (see Fig. 4), whereby through the medium or' these guiding slots, the bar 531.may be moved rearwardly into engagement with the escapement pawl to depress the rear end of the same out of the path of its coperating projection 521b on the escapement rail 521. Bar 531 is held forwardly by means of a spring 532.l A tappet 533 is mounted upon the extreme forward endof the bar 531 to cooperate. with adjustable blocks 534 mounted upon the notched rail 39 of the typewriter carriage. These blocks 534 have pivoted members 535 mounted thereon. The front end of tappet 533 is beveled or inclined as shown in Fig. 4 so that asthetypewriter carriage moves leftwardly, in the, ydirection of the arrow on bar 39, the members 535 will engagethe inclined end of the tappet 533 and g me l cam the-same rearwardly. Upon the return movement of the typewriter carriage to the right, the tappet 533 swings on its pivot in a manner well known without vibrating the bar 531. The tappet 533 is preferably oper ated during the tabulation movement of the typewriter carriage from one column position to another so that each. of the tappets will be engaged, moved rearwardly, and restored to its normal forward position hefore the typewriter carriage completes .its tabulation movement. rThis is essential be cause if the adjustable block 534 were so positioned as to engage and hold its tappet 5.3 rearwardly at a time when the typewriter carriage was stationary, the escapement pawls controlled thereby would effect an incomplete operation, which is undesirable; v

From the above, it will. be observed that the tabulation of the tally roll paper earriage is controlled by the movement of the typewriter paper carriage and in positionu ing the blocks 535 on the latter, it is )ossible to so adjust said blocks that the tzdly roll carriage will be tabulated only at a time when the typewriter paper carriage is moving, either in word printing operations, or in tabulating.

I have not in this application described any means for returning the tal.lyroll carriage, as this is disclosed in said parent case and forms the subject-matter of a com-- panion divisional application tiled by me of even date herewith, SerialNo. 224,961.

What l claim is:

l. In an apparatus of the character de scribed, the combination of a lateraiiy inevafble paper carriage supporting paper to refeeive a printing impression from one set of type, a tallyroll paper carriage porting paper to receive printingimpressi another set of type, a taiiulating mesh --l s a n ei. ehy ceese vel-,y moved to t rate eonnn paper supportco by the First mentioned canWH ringe, said tallyY roll ng slidiely mounted relative to sani easing, and
